Today we went to the Las Vegas Gun Store (hold your political comments for another day) and I saw this. Now I have spotted Braille in the oddest of spots: ATMs that don’t have any audio assistance and maintenance closest signs readily come to mind. This was a tad disturbing and puzzling. Right up there with Braille on a steering wheel.
Somara explained it’s so the gun owner(s) can open the vault in the dark. Sure. Feh! Flesh-eating/Rage-infected zombies can see in the dark and/or are attracted to strong smells, namely panic sweat. Might as well turn on the light, unlock the thing and get to eradicating the undead.
